Market Overview • Release 1 TETRA is almost complete • Growth of Wireless communication • Impact of Internet & 2.5/ 3G on TETRA market • Need for TETRA enhancements is driven by new applications, e.g requiring higher data speeds.
TETRA Release 2 Services & Facilities Not a new Standard but enhancement of the various aspects of TETRA Release 1, viz. • Air Interface • Speech Coding • SIM Evolution • Roaming & Interworking with Cellular • High Speed Data
Air Interface Enhancements • Extending RF Range • Reducing Call set- up Time and End-to-end Delay • Increasing in Subscriber Capacity • Extending Battery Life • Reducing Terminals Size & Weight.
Roaming & Interworking Codec and SIM • Roaming to GSM/ GPRS Systems • Retrieval of WAP Applications • Retrieval of SMS Messages • Use of UMTS/ 3G SIM Technology for Improved Interworking • Use of UMTS/ 3G Codecs to Avoid Double Voice Coding.
TETRA R2 - High Speed Data • IP driven requirement for higher-speed packet data • Two-track approach adopted - TAPS and TEDS, in order to meet conflicting market needs: - of PAMR Operators for Rapid market deployment (overlay TAPS) - for backward compatibility (integrated TEDS)
TETRA Advanced Packet Service - TAPS • An Overlay System • Needs New Infrastructure & Terminals • Data rates up to 384 kbps • 200 kHz Channel Raster • Based on Adaptation of GPRS and Classic EDGE Technologies • Standard Publication expected in early 2002.
TETRA Enhanced Data Service - TEDS • An Integrated System • Technology selection based on User Requirement Specification from EPT Working Group 1 • Four candidate technology currently under consideration in EPT Working Group 4 • Technology selection expected during Q1 2002
Findings from Questionnaire - HSD TEDS • Mandatory requirements • Backward compatibility • Service flexibility • Security compatibility • As marketable as Release 1 • Other important requirements • Ease of Infrastructure upgrade • Minimal need for extra B/Ss • Flexible upgrade to 400kbps • Efficient use of spectrum • Ease of MS upgrade

Present Situation • Set of TETRA Release 2 User Requirement Specifications (URS) has been approved and issued as Technical Report TR 102 021to all the EPT Working Groups • User Workshop has been organised in order to resolve conflicting requirements for HSD • Continued liaison between WG1 and other Working Groups is essential to achieve the right balance and the successful outcome
